Open source desktop tool using advanced AI to enlarge and enhance images without loss of quality, available for Linux, macOS, and Windows. Linux-first development gives early access to Linux users. Requires Vulkan compatible GPU for upscaling.
Cross-platform tool offering advanced video upscaling and frame interpolation using RIFE, RealESRGAN, Waifu2x, and IFRNET, with scene change detection, instant preview, Discord integration, and ability to enhance local files or YouTube videos on major operating systems.
Video2X is a video/GIF/image upscaling software based on Waifu2X, Anime4K, SRMD and RealSR written in Python 3. It upscales videos, GIFs and images, restoring details from low-resolution inputs. Video2X also accepts GIF input to video output and video input to GIF output.
Waifu2x Caffe rewrites only the conversion function of the image conversion software "waifu2x" using Caffe and is software developed for Windows. Although it can convert with CPU, using CUDA (or cuDNN) can convert faster than CPU.
Real-ESRGAN aims at developing Practical Algorithms for General Image/Video Restoration.
Video, Image and GIF upscale/enlarge(Super-Resolution) and Video frame interpolation. Achieved with Waifu2x, Real-ESRGAN, Real-CUGAN, SRMD, RealSR, Anime4K, RIFE, CAIN, DAIN, and ACNet.
Offers enhanced image upscaling to high resolutions with region-based creativity, preservation of facial features, Smart and Dynamic Upscale for detail and composition, generative fill for fixes, precise content control, and minimized manual workflow throughout the process.
Using the latest Deep Convolutional Neural Networks(based on waifu2x). It intelligently reduces noise and serration in images to enlarge them without losing quality. See demo images.
An Android application for super-resolution & interpolation. Contains RealSR-NCNN, SRMD-NCNN, RealCUGAN-NCNN, Real-ESRGAN-NCNN, Waifu2x-NCNN, Anime4kcpp, nearest, bilinear, bicubic, AVIR...
Anime4K is a set of open-source, high-quality real-time anime upscaling/denoising algorithms that can be implemented in any programming language.
Online AI-based platform uses deep learning and Super Resolution to upscale images without losing quality. Fast processing leverages powerful hardware, supports privacy with auto deletion, requires no registration, and works on any device or photo format.
